Thanks, @srgdamiano and @shicks! After working through the code, what seemed to work was actually placing the sensor sleep commands in my getdata() function. For whatever reason it didn’t work too well in the systemSleep function as it seemed to stall my sensors and not allow enough time to wakeup the sensors for reading. Still working on cleaning…[Read more]

@shicks I ended up just going with UART and software serial for now and it works great. I couldn’t get past the interference through the I2C. It seems that for some reason having both sensors on isolated carrier boards plugged into an I2C hub caused interference. As soon as you unplug one of them the other one turns on and the Mayfly functions a…[Read more]

Thanks for troubleshooting the code. Looking at it more…It works with one sensor but not with both on the same I2C hub. It seems that there is a problem when both grounds are connected to the hub with the sleep/RTC pin. I have tried multiple hubs/cables to no avail. Starting to think it is a conflict with one of the sleep functions/libraries…[Read more]

It is sleeping all the time and not waking. No data is being saved or printed to the serial terminal.

Thanks! I worked through a couple of things, including your suggestions, and I still can’t get the logger to wake up… I know the switch works because if I set it to HIGH in the setup the board does come on and the sensors read/turn on without the sleep functions (and the RTC is functioning/correct). Do I need to have a wakeup function or…[Read more]

Hi,
I am having an issue attempting to setup a datalogger to record readings and put the Mayfly to sleep. My setup is an Atlas Scientific EC and temperature probe as I2C protocol connected to an I2C hub. I would like to simultaneously take readings from both of these sensors and save them to the SD card. Meanwhile, have the sensors go to sleep…[Read more]

Hi,
Is there a guide for how to install the GPSbee? Would be interested in using it for a project, but don’t know much about it…
Thanks

Thanks for the help!
I ran into another problem as I think something happened and I blew a chip in the ADCP… I’m trying to determine if voltages were different. The RS232 and 485 chips in the ADCPs are 3.3V and I thought I had everything hooked up correctly to the right voltages, but I’m wondering if the Tx and Rx on the board are 5V output,…[Read more]

Hi Sara,
Thanks for the reply and pointers! I bought an adapter, but I’m unsure if I’m hooking it up correctly. Would you mind looking at the attached pictures for reference? I’m unsure of how the converter takes in serial data and sends it to the Mayfly…

Hi all,
I’m am attempting to hook up an acoustic Doppler current profiler to the mayfly logger to output binary data via RS485 serial (RX0/TXO) as half duplex, 8 bit no parity no stop. Any suggestions on how to go about this? The data output is in this format here: rowetech binary: h…[Read more]
